UNITED STATES PATENT oEE`1E I`IENRY F. POIE, OF CLEVELANDOHIO, ASSGNORTO CASTINGS COMPANY, D F CLEVELAND, OHIO, AA COBPORATIQE To all whom 'it may con-cem? Be it known that 1 HENRY F. POPE, of Cleveland, in `the county of Cuyahoga and State ot' Ohio,.ha\e invented anew and useful Improvement in Radial-Draft Gears, of

'which the following; is a full, clear, and ex act description, reference being had to the accompanying drawings, forming part. of

this specification, in which- Figure l is a plan View of a radial: draft gem constructed in accordance with my inrention; Fig. -2 is :VYertical longitudinal section; Fig. 8 is a Vertical cross section on the line lll- TH of Figf; Fig. lLis an enlarged sectional'vicw similar to Fig. 2; and F 5 is s detailfront View of the 'pivotpm support.

One purpose of my invention isto provide means for the insertion of the pivot, pin connecting the drntt gear tothe car troni be.

strncted. the pivot pin is removed through an 'opening thrmigzfh the floor ofthe earl Another purpose of my invention is to constrnct the end `sill in such-a niannerthat l the central portion thereof is radial substan-V .tialy on the are of motion of the coupler inA Fig. 2,-and inlassenibling the parte a' tei'nporary shim is placed between the regir `head oi the plonger and the fac-eot the bolster. An'annnlar face plate or head 6 is then passed over tbc front end of the plunger 5, and issecnred to the front end of the bracket 2 by ,bolts 7, and when these bolts 'are tightened,tln1s drawing' the head 6 into lace an inward com nession is )ut u on the spring 4.3, Wl1envthe .parte have thus beenhassembled, yan arm 8 Which forms the guidin' arm lorthe 'radialdraft gear, is
